LED PLANE LIGHT SOURCE FOR UNIVERSIAL ILLUMINATION

摘要

A plane light source comprising LEDs is applied to universal illumination. The plane light source mainly contains heat sinks (113), a wiring board (101), LED chips (114), wirings (115) and resins (117) for assembly. Several electrodes (106) are set to electrically connect LED chips on the board, and a circuit layout (107) interconnects the LED chips. Holes (102), where the sinks are embedded, lie in the board. Plurality of holes in parallel forms some pattern. Such LED chips (114) are mounted on the heat sinks. All the LED chips (114) and wirings (115) are one-step encapsulated by the resins. The encapsulation acts as an optical lens.
